This project provides a simple "framework" for profiling request / response times, and sending the data to another service. It includes a base class
Rack::RequestProfiler for handling the logic of wrapping and timing the request / response cycle in a rack app.
By default, the
Rack::RequestProfiler middleware does not do anything with the profiling data. Instead, this logic must be implemented by subclasses by defining the
handle_results instance method. For example, you might send profiling data to an external web service (stathat, papertrail, loggly, etc), statsd, write to a logfile on disk, put it in a persistent store like redis or mongo, or really anything else your heart desires.
This project currently provides profiler middlewares for stathat and statsd. If you'd like to contribute a profiler middleware, pull requests are welcome.
gem install rack-request_profiler
Simply include one of the profiler middlewares into the middleware stack in any rack-compatible application like so:
$statsd = Statsd.new('localhost') use Rack::Profilers::Statsd, $statsd, :ignore_path => /^\/assets/
Be default, we match URL's that look like BSON ids. You can over-ride this regular expression like this:
Rack::Utils::UrlStripper.id_pattern = /some_other_pattern/
